Gould GR37

The GR37, which grew out of the Ralt RT37 Formula 3 car, became the first carbon-fibre chassised car to win a BHC round when David Grace won Harewood in 1996. David & Sean Gould built the car around a DFR engine and Hewland FGC gearbox before steadily developing it into the car to beat by the end of the 90s.

David Grace went on to win three straight titles with his GR37 in ’98, ’99 & ’00.
